BEATING AND REFINING ENGINE FOR PAPER-PULP.

SPECIFICATION forming part of Letters Patent No. 282,098, dated July 31,1883,

Application filed June .20. 1883. (No model.) I

To all whom it may concern.-

Be it known that 1, JOHN J. IVIANNING, a citizen of the United States,and a resident of Great Barrington, in the county of Berkshire and Stateof Massachusetts, have invented certain new and useful Improvements-inBeating and Refining Engines for "Paper-Pulp and I do hereby declarethat the following is a full, clear, and exact description of theinvention, which will enable others skilled inthe art to which itappertains to make and usethe same, referencebeing had to theaccompanying drawings, which form a part of this specification, and inwhich Figure 1 is a side elevation of my improved Fig. 2 is aperspective view of the shaft with its convex grinding-cores. Fig. 3 isa perspective inside view of one of the convex shells with itsfeed-pipe. Fig. 4 is a perspective detailview of one of the headsfitting upon and closing the concave shells.

cave shells relative to the convex. cores; and Fig. 6 is a sectionaldetail view of the receivingchamber at the lower end of the feed-pipewith its pocket. i

' Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to so-called beating and refining engines usedin the manufacture of paper for beating up and refining the pulpyfibers; and it consists in the improved construction and combination ofparts of amachine of that class, as hereinafter more fully described andclaimed, whereby I am enabled to accomplish better work with less powerthan is the case with any other machines of that class withwhich I amacquainted, my improved machine being adapted for use either as a beaterand refiner or as a double refiner,

according to the nature and condition of the stock used in themanufacture of thepaper.

In the accompanying two sheets of drawings, A represents the bed of themachine, upon which are the standards I, forming bearings for the shaftB of the convex rotaryconesC C.

By reference to'Fig. 2 of the drawings it will be seen that shaft B isprovided with annular grooves or corrugations B at the points or placeswhere the shaft is boxedin thestand- Fig. 5 is a detail view, I showingthe mechanism for adjusting the conards I, the boxes being provided withribs or s errations, that fit into the annular corrugations B'", so thatwhile the shaft will rotate freelyin its boxes or bearings it isprevented frommoving in the direction of its length. I further provideshaft B with brass sleeves B at the points where the shaft projectsthrough the stuffingboxes in the apex of the concave shells, and in thecenter of the plate covering the same, one of which plates is shown atPin Fig. 4, the letter Qindieating the stuffing-box. Shaft B is turnedout or reduced in thickness at the points where said brass sleeves areshrunk upon it, so that the shaft will be of even dimensions throughoutits length, except at the points where it is corrugated by the annulargrooves B, for the purpose stated.

A rotary motion is imparted to shaft B and to the convex cores 0 G,which are keyed or otherwise fastened upon it by means of adrivepulley,J, at one end of the shaft.

The stuff, of pulpy fibers, to be beaten and refined isfed into thebeater-shell D fromareceiver, L, and feed-pipe G, the lower end of whichopens up intothe receiving-chamber E, located at the apex of the concaveshell, and

providedwith a stufling-box, through which verse plates, set on edgeparallel to one another, and impinging with their lower edges upon theremovable bottom plate, f, as will appear more clearly by reference tothe detail view, Fig. 6, on Sheet 2 of the drawings. From thereceiving-chamber E the stuff passes into the grinding-chamber inside ofand formed bythe concave beater-shell D, where the pulpy fibers arebeaten and reduced by the knives or cutters on the rotary convex core 0,operating in conjunction with the fixed knives or cutters on the insideof the concave shell I),

The knives or cutters on the cores as well as on the shells are made ofsteel, and arranged as shown in the drawings, with wood fillings betweenthem to hold them firmly in place.

The concave beater-shell D, with its manplate B, is adjustable uponshaft B, relative to the convex core which works inside, in such a andthe inside rotary core.

manner that by adjusting the position of the shell the distance betweenthe knives on its inside and the knives upon the rotary core may beregulated so as to subject the pulpy fibers fed into it to action of theknives, so as to regulate their length. In other words, if the fibersare to be reduced into short lengths, the shell D and rotary core 0 arebrought in close proximity with each other, whereas if it is desired toproduce a pulp with long fibers (according to the class of paper to bemade) the shell D is adjusted in the opposite direction, so as toincrease the distance between it This adjustment may be effected in.various ways, and I prefer for this purpose to use the mechanismillustrated in Figs. '1 and 5 of the drawings. This consists inproviding the adjustable shells D with laterally-proj ecting armsO,having screwthreaded boxes 0 at their outer ends, in which workscrew-threaded shafts N, journaled in bearing-plates I-I, fixed upon thebed-plate A. At one end of each of the shafts N is fixed a gear wheel orpinion, M, which meshes with a worm, L, adapted to be turned by ahandwheel, K. The shaft of this wheel K extends transversely across themachine, its other end being provided with a hand-wheel and worm adaptedto engage a pinion and shaft located on the other side of the machine,so that the adjustment of the concave shell Dmay be effected with theutmost nicety and precision from either side of the machine, and in sucha manner that the shell will work true or squarely forward andback, sothat there is no danger ofits binding upon the central shaft, B, or uponthe threaded rods or shafts N, on which the shell works. I desire atthis stage to say, however, that I do not limit myself to that precisemechanism for effecting the adjustment of the movable shells, as othermeans may be employed by which a like result may be effected.

The obj cct of the brass sleeves B, which work in the stuffing-boxes ofthe movable sh ell, is to prevent the packings from rusting and burningout, these sleeves bcingof such a length as to permit of the adjustmentof the shell without the packings coming in contact with the shaft,except where this is provided with the brass sleeves B.

As the stuff or pulpy fibers are fed into the beatershell D, and theresubjected to the first beating or grinding process, it is expelled'bythe centrifugal force through the dischargepipe G into thereceiving-tank L of the refiner,

which consists of a concave shell, D, covered at its large ends by aman-plate, P, and operating in conjunction with the convex core 0, whichis fixed upon and revolves with shaft B.

The refiner-shell D is made adjustable upon shaft 13 by a mechanismsimilar to that by which I effect the adjustment of the beatershellD-viz. by the hand wheel or wheels K and their connecting-shaft, withits worms intermeshing with the pinions M, one on each side of themachine. Thus it will be seen that the two concave shells D and D may beadj usted independent of each other, the receiving-tank L of shell Dbeing open at the top, so that the discharge-pipe G, which dischargesfrom the beater-shell D into the receiving-tank L, will have sufficientplay in said tank to admit of the adjustment of the two shells D and D.From tank L the stuif or pulpy fibers, as they come from the beater, arerccei ved through pipe Gr in the receiving-chamber E, after theircondition has first undergone examination in the receiving-tank L, forthe purpose of determining the exact adjustment of the beatersliell andrefiner-shell, whereby the best results may be obtained. From therefiner D the pulp isdischarged through the outlet-pipe Inorder toprevent foreign matter contained in the pulpy fibers from entering thebeatershell D, I: provide the pocket F, the constructionof whichhas beenhereinbefore described,

and; the plates 9 of which will intercept foreign substancessuch asbuttons, stones, nails, and other hard substances which have becomemixed with the fibersand prevent them from entering theshell, wheretheir presence would be apt to cause injury to the knives of the retarycone, as well as of the shell. The receiving-chamber E of the refiner Dis provided with a similarly-constructed pocket, F, which will interceptany finer substancessuch as sand or gravelwhich have accidentallypassedthrough with the long fibers from the beater. These impurities mayreadily be removed, whenever desired, by withdrawing th e slidingbottoms from their respective pockets F and F, which may be done withoutstopping the machine or otherwise interfering with its operation.

If desired, the stuff may be fed from the receiving-chambers E and Einto their respective shells by two pipes or inlets located on 0ppositesides of but in proximity to the apices of the shells, so that the stuffis fed into these not through the apex of the shell, but on oppositesides thereof, and on opposite side of claim and desire to secure byLetters Patent of the United States- 1, A beating and refining enginehaving two convex cores fixed upon a rotary shaft, said shaft beingprovided with means for preventing it from moving in its bearings inthe'direction of its length, and provided with a pair of adjustableconcave shells adapted to be adjusted independent of each other inrelation totheir respective cores, substantially as and for the purposeshown and set forth.

2. A beating and refining engine having two convex cores fixed upon arotary shaft, said shaft being provided with means for preventing itfrom moving in its bearings in the direction of its length, incombination with a pair of adjustable shells, one for each of the cores,and means or mechanism for effecting the adjust ment of said shellsrelative to their respective cores, independent of each other,substantially as and for the purpose shown and set forth.

4. I11 a beatingand refining engine, the pockets for interceptingforeign substances contained in the pulpy fiber on its passage to thegrinder shells and cores, said pockets being constructed with a seriesof transverse plates set on edge parallel to oneanother, and providedwith an open bottom having a sliding plate for opening and closing thepocket or receptacle, substantially as and for the purpose shown and setforth.
